Gina | the AS has 3 ranges 1) horizontal range (like in the quiz), where the price level remains constant as domestic output varies 2) upsloping range, where price level and real domestic output can vary 3) vertical range, where real domestic output is constant at FE level and only price level can vary |
am741 | AS: horizontal AD: verticle |
sharon | oh,..I get it now. |
examinee | I don't get it. The above curve means that we can have unlimited supply for a given price. Not sure how and when this will happen. |
zglacier | thanks for Gina. I think she is right. |
hagi10 | AM741. you could not be more wrong. AD is vertical only if the Aggregate demand is 100 % inelastic which is NEVER. |
viannie | hmmm, SR supply curve is pretty flat => that is elastic but not like this one which is horizontal! Unless we are talking about renewable resource such as oil supply. |
dybacis | This would be the Very Short Run Aggregate Supply curve. Firms can react to greater demand in a very short time by increasing labor hours or producing at full capacity but price can't be adjusted that fast so the curve is horizontal |
choas69 | this is not short run aggregate supply this is VERY SHORT RUN AGGREGATE SUPLLY |
sshetty2 | the idea is that price is inelastic in the short-run |
Huricane74 | Agree with @hagi10, dybacis & choas69 |
mikus | "short-run aggregate supply curve typically slopes upward to the right" - your answer here is contradicting notes. |
